(DSM #FQP106) This fossil is exceptional because it shows a partial jaw of a baby mastodon. The molar preserved within still has the high cusps because the animal was not alive long enough for the teeth to be worn down from eating.
(DSM #CH551) It is relatively rare to find a whole mastodon tooth, but fragments of teeth can be regularly found. Often time the cusps are preserved because they are covered in extremely hard enamel.
(DSM #3055) This horse tooth has tooth marks from a rodent that gnawed on the tooth after the horse died. Rodents chew on hard items to keep their teeth healthy.
